as always, context is key. "super good quality" refers to the comparison of the Spitzer and Webb images. it's clear that whever the alignment process is currently (as in, not finished yet), it is far far better resolution and results than the Spitzer was ever able to achieve. this is what has everyone excited. not that there's some artifacts in the image, but that even at this stage of the game it is already much much better and there's still room for improving during further alignment and other software tweaking.
